Glass Balcony at Sears Tower

Our friends from Design Crave shared with us these amazing photos of the recently opened public glass balconies for public viewing. The 1.5″ thick glass floor (which resists up to 5 tons) offers amazing views over Chicago, from 1,353 feet in the air.

As you can see on a picture after the break, the balcony cantilevers from the main structure.
